In browser (Chrome), on desktop (Mac), selecting only a lowercase monster tag as a filter, e.g. to find all 'undead', is providing search results only from MordenKainen's Tome of Foes. e.g., here's a search for 'abberation' (URLs shortened for sanity in this email, but condition same in browser with normal long URL and shortened form): https://www.dndbeyond.com/monsters?filter-type=0&filter-tags=130

Problem not occurring with Monster Tags that begin with a capital letter.
e.g., here's a search for 'Demon': https://www.dndbeyond.com/monsters?filter-type=0&filter-tags=59
For the lowercase problem children, adding a Source I know will have results, e.g. the Monster Manual, yields no results at all:
